FOLDING BED.

Specification of Letters Patent.

Patented Oct, 9, 1 906.

Application filed May 23, 1906. Serial No- 318,370-

To all whom it may concern.-

Be it known that I, J AMES J. BYRNE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Folding Beds, of which the follow ing is a specification.

This invention relates particularly to that class of folding beds in which the head and foot posts on each side ofthe bed are connected together by rails or rods and in which the headposts and the foot-posts, respectively, are connected by lazy-tongs and with a bed-bottom the spring structure of which is mounted on trunnions, so that it can be swung up or let down, by means of which construction the bed can be collapsed or folded to occupy small space.

The object of the present invention is to provide a structure which will not require any looks or contrivances to keep the bed folded.

A further object results in the elimination or omission of any springs or devices to assist in lifting the bed-bottom or to hold it lifted.

A further object of the invention is to simplify and cheapen the construction of such beds, as well as to provide an increase of strength or rigidity.

In the accompanying drawings, Figure 1 is an end elevation of the bed unfolded. Fig. 2 is a similar elevation of the bed folded. Fig. 3 is a front elevation of the bed folded. Fig. 4 is a detail in horizontal section of one of the front posts of the bed on the line 4 4 of Fig. 1. Fig. 5 is a detail in horizontal section of one of the rear posts of the bed on the line 5 5 of Fi 1.

In the construction of the bed the parts at each endthat is, the head and footare identical. The rear posts or side of the bed in the description following will indicate those posts which remain relatively station-.

ary and upon which the folding bottom is pivoted, being the side of the bed, for example, that is placed against a wall toward which the bed is folded. The front posts are the posts which are advanced or retracted from and to the rear posts when the bed is unfolded or folded.

Referring specifically to the drawings, the rear posts are indicated at 6 and the front posts at 7. At the head and foot of the bed,

respectively, the posts are connected by lazytongs 8, which are connected together; in a known manner and pivotally joined at the top to the posts, as indicated at 9. The lower and intermediate connections of the lazy-tongs with the posts are produced by pivot-pins at 10 and 11, which slide,.respectively, in vertical grooves 12 and 13 in castings 14 and 15, secured to the posts.

The rear posts 6 are connected together by side rails or rods 16 and 17. The former is located above the bed-bottom, and the latter is located near the foot of the posts. These two rods form a rigid support or connection for the posts, and the upper rod 16, being located above the bed-bottom, does not interfere with the swing of the rear edge of said bottom incident to the folding operation. The front posts 7 are connected together by side rods 18 and 19, fixed to the posts, and these rods are necessarily located below the bed-bottom, so as to be out of the way of the lift.

The bed-bottom or spring-frame is indicated at 20. It has at the ends depending brackets 21 from which project laterallyextending trunnions 22, which fit in notches 23 at the outer ends of arms 24, which proj ect from the castings 15, secured to the rear posts. The brackets and trunnions are located some distance forwardly from the rear posts by means of the arms 24, which are extended and also dropped to bring the pivotpoint such a distance forward that when the bed-bottom is lifted and folded it will swing inwardly beyond the perpendicular, as shown .in Fig. 2, and hence will remain in that posispring-frame strikes when in upright position.

The bed-bottom is connected to the front posts by means of links 26 at each end thereof, the links being preferably bent slightly, as shown, in order to give a more direct pull and thrust. When the front side of the bedbot tom is lifted, the links pull the front posts inwardly, and thus collapse the lazy-tongs, and when the bed-bottom is pulled down or curtain may be hung, if desired.

I claim 1. In a folding bed, the combination of front and rear posts, connections between them, a bed-bottom pivotally supported on the rear posts, and longitudinal rods connecting the two rear posts, one of said rods being located above the bed-bottom and the other below it.

2. In a folding bed, the combination of front and rear posts, folding connections between them, arms projecting forwardly from the rear posts, a bed-bottom pivoted at its ends upon the front end of said arms, at a distance from the rear edge of said bottom, and fixed stops extending from the rear posts below said bed-bottom and projecting beside the ends of the bed-bottom in position to engage the said ends when swung down.

3. In a folding bed, the combination of front and rear posts, lazy-tong connections between the same, arms projecting forwardly from the rear posts and dropped below the bed-bottom, a bed-bottom having depending brackets and trunnions at a distance from the rear edge thereof, and rigid stops extending from the rear posts, below said arms and projecting beside the ends of the bed-bottom into osition to be struck by the head and foot ars of the bed-bottom when it is swung beyond the vertical.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
